Ambient Light Sensor: Spectral Range 400-700 nm

Q: How does an ambient light sensor improve LED lighting efficiency?

By automatically dimming LED lights when sufficient natural light is available and increasing brightness when needed, reducing energy consumption by 20-60% while maintaining optimal illumination levels

Q: What maintenance do ambient light sensors require?

Minimal maintenance - periodic cleaning of the lens surface to prevent dust accumulation that could affect light measurement accuracy, typically every 6-12 months depending on environment

Q: Can ambient light sensors work in extreme temperature conditions?

Industrial-grade sensors are rated for -40°C to +85°C operation with temperature compensation circuits to maintain accuracy across the full range
